Google has posted the updated JRO03H (Android 4.1.1) closed binary files today, including those for the Nexus S4G. That means one thing -- expect about a bazillion new AOSP Jelly Bean ROMs to be ready for download shortly, especially for the Sprint Nexus S. Before you ask, this has nothing to do with any OTA. These are the files that folks need to build Jelly Bean from the source code, and get everything working like it should. Developers have been working with the existing 4.1.1 source code since it dropped, but with these files there's 100-percent less hackery needed to get things like cameras, NFC, and Wimax working as intended on supported phones. While we see new files for the GSM Nexus phones, the Xoom, and even the Verizon Galaxy Nexus, Sprint's Galaxy Nexus is still absent.

As we saw when the Ice Cream Sandwich binaries were released, it could be more than a month until Google and Sprint get any OTA worked up, so this is a solid option if you need the butter. We all love the butter.

Don't fret if you're not up to speed with things like fastboot and flashing, because there's a great group of fellows in the Nexus S 4G forums who live to play with this sort of thing. Head in there, poke around a bit, then holler for any help you need. You'll be running Jelly Bean in no time.
